> The Quata class's andByStorageType method res has an incorrect initial value

> Key: HDFS-17214
> URL: https://issues.apache.org/jira/browse/HDFS-17214
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: rbf
> Affects Versions: 3.3.4
> Reporter: xiaojunxiang
> Priority: Major
> Labels: pull-request-available
>
> The Quata class's andByStorageType method is intended to apply bitwise and to
> each bit of StorageType.values( ) (the converted value), returning true only
> if all the values are true.
> So the initial value of res should be true and then loop through the array to
> perform the bitwise and operation.
> However, since res starts with fasle, the bitwise and always evaluates to
> false, so we should fix res to start with true.
